A Rocklin couple received a phone message stating that the sheriff's department would be on their doorstep in 20 minutes with an arrest warrant if they did not pay nearly $10,000.

The family reported that the caller was extremely aggressive and very convincing.

Rocklin Police Department Capt. Lon Milka said his office has received similar complaints.

"If someone calls demanding money, don’t send them money. Get a name, a phone number get some way to call them back. If you still feel unsafe you can always call the police department. We’ll be more than happy to check that out and see if it sounds familiar. We’ve had a lot of scams going on right now," said Milka.

The treasury inspector general for tax administration said the office has tracked over 60,000 claims of fraud in which it says victims have shelled out more than $4 million.

Victims reported getting a call from someone claiming to be an agent with the Internal Revenue Service who is calling to collect unpaid taxes.

The callers are aggressive and in most cases have warned that if the phone is disconnected before the issue is resolved, police will be sent with an arrest warrant.

The callers demand that payment must be made using a pre-paid debit card or other form of electronic transfer.

The IRS warns that it typically contacts citizens by mail before ever making a phone call and the agency would never threaten arrest.

Lilka added his agency does not call before coming to make an arrest either.

The treasury inspector general for the tax administration has set up a web page for citizens to report suspicious calls.
